MPQ4488TGU-FD2-AEC1-P

Overview

The MPQ4488TGU-FD2-AEC1-P is a monolithic three-output synchronous buck switching regulator from Monolithic Power Systems, designed for automotive applications. It features a wide input voltage range of 6 V to 36 V and delivers up to 6 A per channel. The device integrates internal power MOSFETs and operates at a fixed switching frequency of 2.2 MHz. It provides three independent outputs with voltages including 5.1 V, 5.17 V, and 5.3 V. The component is housed in a QFN-26 package and meets AEC-Q100 qualification standards for operation between -40°C and +125°C.

Feature Summary

• Three independent synchronous buck channels providing isolated output regulation
• Wide input voltage capability supporting 6 V to 36 V supply ranges
• Integrated high-frequency switching architecture eliminating external inductors for some configurations
• Automotive-grade reliability compliant with AEC-Q100 standards

Applications

• Infotainment system power distribution
• Instrument cluster voltage regulation
• ADAS sensor power supplies
• Telematics unit power management

Procurement Notes

Verify the specific suffix FD2 against official MPS documentation to confirm pinout and electrical characteristics, as suffixes often denote tape-and-reel packaging or specific factory codes rather than functional changes. Confirm availability status as this part may be subject to lifecycle restrictions such as NRND status. Ensure the ordering code matches the exact required output voltage configuration and package variant before procurement.

Selection Notes

Select this component when designing systems requiring three regulated rails from a single wide-input source. It is suitable for space-constrained automotive PCB layouts due to its integrated topology. Engineers should verify thermal performance under maximum load conditions given the 6 A per channel rating. Consider the 2.2 MHz switching frequency for EMI management and passive component size optimization compared to lower-frequency alternatives.

Part Context

This part belongs to the MPQ4488 series of multi-output DC-DC converters. It is distinct from single-output regulators by integrating three complete buck channels into one IC. The series is targeted at automotive PMIC applications where board space and component count are critical constraints. It complements other MPS automotive solutions by providing consolidated power management for complex electronic control units.

Replacement Considerations

Official recommendations suggest MPQ4488BGU-AEC1-Z or MPQ4488BGU-FD-AEC1-Z as alternatives for new designs. Verify compatibility regarding output voltage options and package dimensions before substitution.
